If you remember rocking out to Google's play-it-yourself guitar logo honoring legendary bluesman Les Paul, you'll be pleased to know that Google's at it again with another instrumental creation.
Google is celebrating May 23, which would have been Dr. Robert Moog's 78th birthday, with an interactive homepage logo that looks and plays like a Moog synthesizer. You can use the cursor to adjust the synth's oscillators, pound on the keys, apply filters and even record and share your own synthesizer creations. At the right-hand side of the doodle, the animated recording equipment generates a sharable link of your creation for you to copy and paste; there's even a G+ button, for Google+ users to post their songs directly to the social network.
(Google's U.S. users got early access to the doodle on May 22 by visiting Google's Australia homepage when the doodle went live at midnight on May 23, local time. Hat tip to Mashable for pointing this out.)
Dr. Moog, who died in 2005 at age 71, released the first iteration of his synthesizer in 1964. His instrument has inspired generations of musicians, from avant-garde and experimental composers to mind-expanding rock and more conventional pop acts.
Dr. Moog and his synthesizer were also the subjects of a 2004 documentary titled "Moog." Check out a clip from the film:
